BC: Prototyping

Once we have an idea of the schematic and the circuit itself, it's time to test the simulations in real life: Depending on the project, we can test all the circuits or just the specifics parts that are in doubt. For this task, It is highly recommended to use tools such as breadboards, stripboards, some wires and a huge amount of patience.

As the first test, we just wanted to test if it was possible to turn on the display, and see which frequency should we use to get an acceptable brightness:

After we tested a plain schematic without any transistor, battery or buzzer and with an experimental code, it was time to get the hands into work with a soldered version in a stripboard:

As you can see, here we used the battery to test if we were able to supply the complete PCB from a CR2032 cell. An ICSP port is also installed for fast coding. So this stripboard helped us a lot in terms of coding new versions into the device.

The next step was clearly the PCB Design and assembly. Here is the final result:

In the next chapter, we will show How we assembled everything and how it was validated. Thanks for reading!, do not forget to follow us on Instagram if you want to be updated with the latest news.
